KEEP ALL PARTS OF YOUR BODY 

away from the saw

chain when the engine is running.

ALWAYS CARRY THE CHAINSAW WITH THE ENGINE
STOPPED AND THE BRAKE ENGAGED,

 the guide bar

and saw chain to the rear, and the silencer away from
your body. When transporting the chainsaw, use the
appropriate guide bar scabbard.

DO NOT OPERATE A CHAINSAW THAT IS DAMAGED,

improperly adjusted, or not completely and securely
assembled. Be sure that the saw chain stops moving
when the throttle control trigger is released.

TURN OFF THE ENGINE 

before putting the chainsaw

down. 

DO NOT

 leave the engine running unattended.

As an additional safety precaution, apply the chain brake
before putting down the saw.

USE EXTREME CAUTION 

when cutting small-size

brush and saplings because slender material may catch
the saw chain and be whipped toward you or pull you
off balance.

WHEN CUTTING A LIMB 

under tension, be alert for

spring-back so that you will not be struck when the
tension in the wood fibres is released.

KEEP THE  HANDLES

 dry, clean, and free of oil or

fuel mixture.

OPERATE THE  CHAINSAW  ONLY

 in well-ventilated

areas.

DO NOT OPERATE A CHAINSAW IN A TREE 

unless

you have been specifically trained to do so.

ALL CHAINSAW SERVICE, 

other than the items listed

in the instruction manual and all maintenance, should
be performed by competent chainsaw service personnel.
(For example, if improper tools are used to remove the
flywheel or if an improper tool is used to hold the
flywheel in order to remove the clutch, structural
damage to the flywheel could occur and subsequently
cause the flywheel to burst.)

KEEP SAFE-T-TIP® ANTI-KICK-BACK NOSE GUARD

properly mounted on the guide bar to prevent rotational
kick-back.

FOLLOW THE SHARPENING

 and maintenance

instructions for the saw chain.

USE ONLY THE REPLACEMENT GUIDE BARS

 and low

kick-back chains specified for your saw.

DO NOT

 adapt your powerhead to a bow guide or use

it to power any attachments or devices not listed for
your saw.

SAVE THESE INSTRUCTIONS. 

Refer to them

frequently and use to instruct other users. If you lend
someone this tool, lend them these instructions also.

WARNING:

The warnings, labels, and instructions found in this
section of the operator’s manual are for your safety.
Failure to follow all instructions may result in serious
personal injury.

GENERAL PRECAUTIONS

DO NOT CUT VINES

 and/or small undergrowth (less

than 76 mm (3 in.) in diameter).

SILENCER SURFACES ARE VERY HOT 

during and

after operation of the chainsaw; keep all body parts
away from the silencer. Serious burns may occur if
contact is made with the silencer.

ALWAYS HOLD THE CHAINSAW WITH BOTH HANDS

when the engine is running. Use a firm grip with thumbs
and fingers encircling the chainsaw handles.

NEVER LET ANYONE USE YOUR CHAINSAW

 who

has not received adequate instructions in its proper use.
This applies to rentals as well as privately owned saws.

BEFORE YOU START THE ENGINE

, make sure the

saw chain is not contacting any object.

OPERATE THE CHAINSAW

 only in well ventilated

areas.
